範例

以下範例展示了如何建立通道工廠，並用它來建立和管理通道。

    BasicHttpBinding binding = new BasicHttpBinding();
    EndpointAddress address = new EndpointAddress("http://localhost:8000/ChannelApp");

    ChannelFactory<IRequestChannel> factory =
        new ChannelFactory<IRequestChannel>(binding, address);

    IRequestChannel channel = factory.CreateChannel();
    channel.Open();
    Message request = Message.CreateMessage(MessageVersion.Soap11, "hello");
    Message reply = channel.Request(request);
    Console.Out.WriteLine(reply.Headers.Action);
    reply.Close();
    channel.Close();
    factory.Close();
}

以下程式碼範例展示了如何在工廠建立通道物件之前，以程式方式插入客戶端行為。

public class Client
{
  public static void Main()
  {
    try
    {
      // Picks up configuration from the config file.
      ChannelFactory<ISampleServiceChannel> factory
        = new ChannelFactory<ISampleServiceChannel>("WSHttpBinding_ISampleService");

      // Add the client side behavior programmatically to all created channels.
      factory.Endpoint.Behaviors.Add(new EndpointBehaviorMessageInspector());

      ISampleServiceChannel wcfClientChannel = factory.CreateChannel();

      // Making calls.
      Console.WriteLine("Enter the greeting to send: ");
      string greeting = Console.ReadLine();
      Console.WriteLine("The service responded: " + wcfClientChannel.SampleMethod(greeting));

      Console.WriteLine("Press ENTER to exit:");
      Console.ReadLine();

      // Done with service.
      wcfClientChannel.Close();
      Console.WriteLine("Done!");
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine("The service operation timed out. " + timeProblem.Message);
      Console.Read();
    }
    catch (FaultException<SampleFault> fault)
    {
      Console.WriteLine("SampleFault fault occurred: {0}", fault.Detail.FaultMessage);
      Console.Read();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine("There was a communication problem. " + commProblem.Message);
      Console.Read();
    }
  }

Public Class Client
  Public Shared Sub Main()
    Try
      ' Picks up configuration from the config file.
      Dim factory As New ChannelFactory(Of ISampleServiceChannel)("WSHttpBinding_ISampleService")

      ' Add the client side behavior programmatically to all created channels.
      factory.Endpoint.Behaviors.Add(New EndpointBehaviorMessageInspector())

      Dim wcfClientChannel As ISampleServiceChannel = factory.CreateChannel()

      ' Making calls.
      Console.WriteLine("Enter the greeting to send: ")
            Dim greeting As String = Console.ReadLine()
      Console.WriteLine("The service responded: " & wcfClientChannel.SampleMethod(greeting))

      Console.WriteLine("Press ENTER to exit:")
      Console.ReadLine()

      ' Done with service. 
      wcfClientChannel.Close()
      Console.WriteLine("Done!")
    Catch timeProblem As TimeoutException
      Console.WriteLine("The service operation timed out. " & timeProblem.Message)
      Console.Read()
    Catch fault As FaultException(Of SampleFault)
      Console.WriteLine("SampleFault fault occurred: {0}", fault.Detail.FaultMessage)
      Console.Read()
    Catch commProblem As CommunicationException
      Console.WriteLine("There was a communication problem. " & commProblem.Message)
      Console.Read()
    End Try
  End Sub

備註

此通用類別允許更進階的情境，需要建立一個通道工廠，以建立多種通道類型。

在程式化新增行為時，行為會在建立任何通道前，先加入適當的 Behaviors 屬性 ChannelFactory 。 請參見範例部分的程式碼範例。

通常使用此類型的客戶端或呼叫應用程式（例如中階應用程式也是客戶端應用）也有複雜的狀態管理需求與效能需求。 欲了解更多相關情境資訊，請參閱 Middle-Tier 客戶應用程式。
